The Karran Q-309-BR is a single-bowl undermount vanity sink in Brown, made from quartz composite and sized to fit a 24-inch or wider vanity cabinet. It mounts beneath laminate, solid surface, or granite countertops for a clean, rimless finish at the bowl edge.
An undermount sink attaches below the countertop so the deck runs continuously to the bowl opening with no rim or lip sitting proud of the surface. That detail matters in a bathroom: water wiped off the counter goes straight into the bowl rather than catching on a sink rim. For a vanity that sees daily use, it also means one fewer seam to keep clean. This sink fits countertops in laminate, solid surface, and granite, which covers a wide range of vanity builds from budget-friendly laminate tops to stone.
Quartz composite sinks are made from crushed quartz blended with resin binders, producing a dense, consistent material that reads as stone without being a single slab. The Brown finish on the Q-309-BR is a warm, mid-tone neutral that works against darker cabinet stains, walnut and espresso finishes, and natural wood vanities where a white or light sink would read as a stark contrast. It also coordinates well with bronze and brushed gold faucet hardware. The quartz surface is non-porous, which means it does not absorb staining agents the way an unfinished or porous material would.
This is a bathroom vanity sink sized for a 24-inch or larger cabinet, so it fits the single-sink vanities common in full baths, guest baths, and powder rooms. The 20 by 14 inch footprint is compact enough for a smaller vanity without sacrificing usable bowl depth. It suits remodels and new builds alike, as long as the countertop is laminate, solid surface, or granite and the cabinet meets the minimum width. Designers specifying for a warm or nature-inspired bathroom palette will find the Brown finish fits without requiring a custom countertop color match. Cabinet shops and contractors building out a vanity with a darker stain profile can treat this as a straightforward sink selection that holds its own against richer wood tones.
No. The Q-309-BR is an undermount-only sink. It is not designed for drop-in or top-mount installation.
It is designed for undermounting into laminate, solid surface, and granite countertops. If your countertop is a different material, confirm compatibility before ordering.
The minimum cabinet width required is 24 inches. The sink itself is 20 inches wide by 14 inches deep, so confirm your cabinet's interior dimensions before ordering.
The source does not confirm drain or mounting hardware is included. Plan to source a drain fitting separately sized for the 1-3/4 inch drain opening.
No. This sink is not ADA compliant per the product specifications.
The Q-309-BR in Brown brings a sink that sits quietly but confidently in a warm vanity palette, mounts clean beneath the counter, and is built from a quartz composite that holds up to daily bathroom use.
